Managing licensed and unlicensed communications using cellular protocols

1. A method of managing licensed and unlicensed communications over a cellular protocol, comprising the steps of: (a) wirelessly transmitting a communication session request from a wireless device to a wireless carrier system using the cellular protocol, wherein the communication session request is transmitted over a licensed communications frequency band as a part of an attach procedure; (b) receiving a response at the wireless device from the wireless carrier system as a part of the attach procedure, wherein an inspection of information in the response provides an indication that either the wireless carrier system is providing a communication session using the licensed communications frequency band or the wireless carrier system is providing a communication session using an unlicensed communications frequency band; (c) determining whether to establish communications via the licensed communications frequency band or the unlicensed communications frequency band based on the content of the communications that are to be carried out with the wireless carrier system; and (d) establishing communications from the wireless device via the wireless carrier system based on whether the wireless carrier system is providing cellular communications via the licensed communications frequency band or the unlicensed communications frequency band, wherein the establishing step includes: when it is determined to establish communications via the licensed communications frequency band and when it is determined that the wireless carrier system is providing cellular communications via the unlicensed communications frequency band, then repeating the attach procedure including steps (a) and (b) until the wireless carrier system provides cellular communications via the licensed communications frequency band.

2. The method of claim 1 , wherein the wireless device further comprises a vehicle telematics unit.

3. The method of claim 1 , wherein the cellular protocol further comprises 4G LTE.

4. The method of claim 1 , wherein steps (a), (b), and (d) further comprise wireless communications between the wireless device and a cell tower.

5. The method of claim 1 , wherein the unlicensed communications frequency band further comprises the frequencies identified by a specification set forth in IEEE 802.11.

6. The method of claim 1 , further comprising the step of storing the indication of a licensed communications frequency band in usage records at the wireless carrier system.

7. A method of managing licensed and unlicensed communications over cellular protocol, wherein the method is carried out by a wireless device, comprising the steps of: (a) wirelessly transmitting a communication session request from the wireless device to a wireless carrier system using the cellular protocol; (b) receiving a response at the wireless device from the wireless carrier system indicating that the wireless carrier system is providing a communication session using a licensed communications frequency band or an unlicensed communications frequency band; (c) determining from the response whether the wireless carrier system is providing cellular communications via the licensed bandwidth or the unlicensed bandwidth; (d) identifying a node from a plurality of nodes that is to be contacted by the wireless device via the communication session; (e) determining whether to use the licensed communications frequency band or the unlicensed communications frequency band based on the identified node, wherein the wireless device stores the plurality of nodes in memory of the wireless device along with a preference for the licensed communications frequency band or the unlicensed communications frequency band, and wherein the determination of step (e) is made based on inspecting the preference of the identified node as stored in memory of the wireless device; (f) determining whether the communication session uses a frequency band that corresponds to the frequency band as indicated by the preference of the identified node; and (g) when it is determined that the communication session uses a frequency band that corresponds to the determined frequency band of step (e), establishing communications via the wireless carrier.

8. The method of claim 7 , wherein the wireless device further comprises a vehicle telematics unit.

9. The method of claim 7 , wherein the cellular protocol further comprises 4G LTE.

10. The method of claim 7 , wherein steps (a)-(d) further comprise wireless communications between the wireless device and a cell tower.

11. The method of claim 7 , wherein the unlicensed communications frequency band further comprises the frequencies identified by a specification set forth in IEEE 802.11.

12. The method of claim 7 , further comprising the step of determining whether to establish communications via the licensed communications frequency band or the unlicensed communications frequency band based on the content of the communications.

13. The method of claim 7 , further comprising the step of storing an indication of a licensed communications frequency band in usage records at the wireless carrier system.
